Acacia (uh-kay-sha) and Adira (uh-deer-uh) aren't your average twin. They have a haunting past. They never speak of their family or where they came from. All anyone knows is that they appeared out of thin air. Almost quite literally. Harry and his gang become involved with the twins when they realize Dumbledore is frightened about the girls residing at the castle. Then Trouble starts when Harry falls in love with one of them, and Draco the other.
